Industrial energy consumption is massive, but thermal storage can boost energy efficiency

April 5, 2019 | 64 views

Energy demand in the industry is often in the form of thermal energy steam, heat or hot water, and cooling. The greater part of global steam and hot water production continues to be based on the use of fossil energy sources. Depending on temperature needs, cooling is achieved using either sea water or large cooling plants. The latter incur huge investment costs and can be operationally challenging under conditions of fluctuating demand.

Renewables find success in ‘black start’ experiment

Article | June 14, 2022

Have you ever thought about what would happen if a power station failed? Without electricity to bring itself back online, it would be near impossible for a station to begin operating again, like trying to set fire to paper without a flame. This scenario would quickly lead to widespread chaos, with hospitals and schools plunged into darkness, refrigeration, and sanitation seriously hampered and transport systems brought to a standstill. For these reasons (and many, many more), governments and electricity networks often have complex and rigorous plans in place to bring dead power stations back online at the earliest.

Treasury Wine Estates To Install Thousands Of Solar Panels

Article | June 8, 2022

The company behind famous Australian wine brands including Penfolds and Wolf Blass is embracing solar energy in a big way. ASX-listed Treasury Wine Estates (TWE) is one of the world’s largest wine companies and has an ambition to be the “world’s most admired premium wine company”. A powerful way to win consumer hearts, minds (and wallets) these days is to have a strong focus on sustainability. As part of its sustainability mission, wines in TWE’s portfolio will be produced using 100% renewable electricity by 2024. In a step towards this renewables goal in Australia, approximately 9,500 solar panels will be installed at Barossa Winery and Production Centre in South Australia, and Karadoc Winery in Victoria by the end of this year. Collectively, the solar panels will generate more than 5,500 megawatt-hours of electricity annually, enough to supply the equivalent of 900 homes. Total capacity wasn’t mentioned, but given the annual output, I’d estimate it at around 3.75 MW.

A vision for renewable energy

Article | February 11, 2020

Right now, renewable energy makes up a very small part of the entire energy sector of Bangladesh. But as we move into the future, and concerns about the environment become too great to ignore, exploring cleaner and greener sources of energy becomes the need of the hour. Our economy is booming, and our population is growing, so it goes without saying that our energy requirements are immense. There is plenty of scientific evidence that burning fossil fuels indiscriminately is not sustainable in the long term, so we do need to up our game in looking at alternatives.

2020: The Year of Convergence in Corporate Renewables

Article | February 10, 2020

The rapid growth of corporate renewable procurement has been nothing short of a buyer-driven revolution in the United States’ electric sector. Almost 20 gigawatts (GWs) of corporate power purchasing agreements (PPAs) were completed in 2019 across the globe, up from 13 GWs of corporate PPAs in 2018 and triple the numbers from 2017.1,2 And the majority of this growth has come from the United States. Fortunately for those of us committed to renewable energy, we expect this trend to continue. But as should be expected in such a dynamic, buyer-driven sector, we are starting to see some noticeable shifts in the marketplace as it evolves and grows. I wanted to highlight some of the trends Constellation is watching for this year.

Colorado’s Solinator Garden completed by Solaris Energy and Namasté Solar

Solar Builder | November 11, 2019

Solaris Energy and Namasté Solar – two Colorado-based solar firms that work nationwide – have completed The Solinator Garden, a 1-megawatt solar array at Kyle Ave in Fort Collins. The system involved over 100 Colorado-based people, including staff at Namasté Solar, Solaris Energy, and the Fort Collins Utilities as part of their Solar Power Purchase Program (SP3). “When cities like Fort Collins partner with local businesses like Namasté Solar and Solaris Energy, it magnifies the impact on the local economy, and it creates well-paying green jobs within the community,” said Jason Sharpe, chief executive officer, and coowner at Namasté Solar. SP3incentivizes the installation of new, local commercial-scale solar systems owned and maintained by companies such as Solaris Energy. The Solinator Garden is named to highlight the project’s use of land underneath and around the solar panels to provide a healthy habitat for local pollinator species. Climate change has already had a negative impact on insect and bird populations in Colorado. Land around solar arrays can be used for productive purposes in addition to creating clean, renewable energy.

California: Renewables sustain groundwater sustainability

ESI Africa | November 11, 2019

Solar and wind farms are popping up around the US to lower carbon emissions, and these renewables also have another important effect: keeping more water in the ground. A new Princeton University-led study in Nature Communications is among the first to show that solar and wind energy not only enhance drought resilience, but also aid in groundwater sustainability. Using drought-prone California as a case study, the researchers show that increased solar and wind energy can reduce the reliance on hydropower, especially during drought. Consequently, this could help divert more surface water from hydropower to irrigation, thereby reducing overall groundwater abstraction. While the scope of this study focused on the US, the framework can also be applied internationally, especially for policymakers working to meet the UN’s Sustainable Development Goals, said lead author Xiaogang He, who worked on the study as a Ph.D. student at Princeton. He is now a Water in the West postdoctoral fellow at Stanford University. “Traditionally, the social value of solar and wind energy has mostly been focused on air pollution mitigation and carbon emission reductions,” said He, an incoming assistant professor in the department of Civil and Environmental Engineering at the National University of Singapore.

Hawaiian Electric Companies issue call for projects to accelerate islands' renewable energy transition

Energy Global | November 11, 2019

The Hawaiian Electric Companies, subsidiaries of Hawaiian Electric Industries Inc. are beginning the largest procurement effort for renewable energy resources in Hawai'i, US. The aim is to end the use of coal and reduce reliance on imported oil for power generation in order to move the state closer to its goal of using 100% renewable energy by 2045. With the approval of the Public Utilities Commission (PUC), the companies have issued requests for proposals for renewable energy and grid services from developers locally and globally. Details are at www.hawaiianelectric.com/competitivebidding. Approximately 900 MW of new renewables or renewables paired with storage -- generating about 2 million MWh annually -- are sought. This includes estimated targets of technologies equal to 594 MW of solar for O'ahu, 135 MW for Maui and up to 203 MW for Hawai'i Island. Projects for Maui must include energy storage. On Hawai'i Island, solar must include storage but is optional for other technologies. On O'ahu, pairing generation with energy storage is optional. Storage on O'ahu and Maui is also being sought to replace firm generating units. This can be provided by renewable generation paired with storage or standalone storage.
